Abstract
A tire pressure sensing device for a tow trailer that signals the driver of the tow vehicle subsequent to deflation of at least one tire mounted to the trailer. The tire pressure sensing device further includes a base plate mounted to the axle of the tow trailer releasably secured by a generally u-shaped clamp. A switch is superposed on the base plate. The switch further includes an actuating rod support member and an actuating rod extending in a downward direction. The actuating rod biases the switch to a closed position subsequent to deflation of the tire thereby electrically activating a warning indicator.
Claims17
A device for detecting low tire pressure for a tow trailer, comprising:
- a switch supported on a base plate and positioned proximate at least one tire of the tow trailer, said switch switchable between an open position and a closed position, said switch being a normally open switch;
- said base plate configured to be mounted adjacent to an axle of the tow trailer;
- a mounting clamp mounted around the axle to support the base plate;
- said mounting clamp having two ends;
- said two ends releasably secured to said base plate;
- an actuating rod support member mounted to the base plate and pivotally connected to said switch, for supporting an actuating rod that is operable to switch said switch between said open position and said closed position;
- said actuating rod surroundably mounted to one end of the actuating rod support member and tightened by a strap on a side of the base plate opposite the switch;
- said actuating rod extending downward to a predetermined point proximate the ground surface under the tow trailer;
- and
- a warning device connected to said switch and operable when said switch is in said closed position;
- wherein when said actuating rod engages the surface under the tow trailer when the tire pressure of the tow trailer drops to a determined level said actuating rod switches said switch to said closed position.
A pressure monitoring and warning device for monitoring the pressure of at least one tire of a tow trailer, said pressure monitoring and warning device comprising:
- a switch supported on a base plate and mounted proximate the tire of the tow trailer, said switch switchable between on open position and a closed position, said switch being a normally open switch;
- an actuating rod support member mounted to the base plate and pivotally connected to said switch, said actuating rod operable to switch said switch between said open position and said closed position;
- a warning device connected to said switch and operable when said switch is in said closed position;
- an actuating rod surroundably mounted to one end of the actuating rod support member and tightened by a strap on a side of the base plate opposite the switch;
- said actuating rod extending downward to a predetermined point proximate the ground surface under the tow trailer;
- and
- wherein when said actuating rod engages the surface under the tow trailer when the tire pressure of the tow trailer drops to a determined level said actuating rod pivots thereby switching said switch to said closed position.
A pressure monitoring and warning device for monitoring the pressure of at least one tire of a tow trailer, said pressure monitoring and warning device comprising:
- a switch supported on a base plate and mounted proximate the tire of the tow trailer, said switch switchable between an open position and a closed position, said switch being normally open switch;
- a mount configured to releasably receive said switch;
- an actuating rod support member mounted to the base plate and connected to said switch, said actuating rod operable to switch said switch between said open position and said closed position;
- an actuating rod surroundably mounted and generally contiguous with one end of the actuating rod support member by a strap opposite the switch;
- said actuating rod extending downward to a predetermined point proximate the ground surface under the tow trailer;
- a warning device connected to said switch and operable when said switch is in said closed position;
- wherein when said actuating rod engages the surface under the tow trailer when the tire pressure of the tow trailer drops to a determined level said actuating rod switches said switch to said closed position.
